OLIGOMERIC AMIDOAMINES OR AMIDO-SUBSTITUTED QUATERNARY AMMONIUM COMPOUNDS FOR TREATING FABRIC OR HAIR Russian patent published in 2010 - IPC C08G59/54 C08G69/34 C11D1/62 C11D3/37 A61Q5/12 

FIELD: chemistry.

SUBSTANCE: invention relates to hair conditioning and fabric softening aqueous compositions which contain an effective amount of an oligomeric amidoamine and water, wherein the oligomeric amidoamine contains a reaction product (A), (B) and (C), where (A) is alkylene polyamine having formula: , where R¹, R², and R³ independently denote H or -R⁵-N(R⁴)₂, where not all of R¹, R² and R³ denote H; R⁴ denotes H or -R⁵-N(R⁸)₂; R⁸ independently denotes H or R⁵; and R⁵ denotes (i) a C₁-C₂₃ alkylene or alkenyl group which is optionally substituted or branched; or (ii) an aryl group; (B) is a dicarboxylic acid or reactive derivative of such an acid, having formula HOOC-R⁵-COOH, where R⁵ is as defined above; and (C) is (i) a fatty acid having formula R⁶-COOH, where R⁶ denotes a straight or branched C₆-C₂₃ alkyl or alkenyl group; and/or (ii) alkyl ether or fatty glyceride (i), a salt of oligomeric amidoamine and/or oligomeric amido-quaternary oligomeric amidoamine. The invention also relates to fabric softening and hair conditioning methods, involving contact between hair and fabric and a sufficient amount of said compositions.

EFFECT: increase in aligometic amidoamine and its quaternary compounds while preserving softening efficiency and capacity to retain light or transparent or semitransparent compositions.
